Broker qs File size keeps increasing

Hi All,
Recently broker qs file was full so i created a new qs store and the problem is solved. now the new store file i created is also getting full, it is only 3 days i have created this file. i check the client queues none of them have more than 10 document. i though it might be the problem of broker log getting full checked the same but it is olny 5mb. can some body please suggest some thing.

Thanks in advance


Finally i managed to find out what is the problem. i am posting the answer feeling this might be useful to some one. Broker was in territory and the forward client for this queue is full, i cleared the forward client and then file size reduced.
